Method for forming Chinese medicinal suppository

Abstract

A method for forming Chinese medicinal suppository includes preheating and bonding that foam-shaped area on sheet material smaller than producing foam-shaped area through preform die to form inner foam-shaped area, pressing the outer side of inner foam-shaped area through forming die to form outer foam-shaped area, and leaving a distance between inner foam-shaped edge and inner edge of outer foam-shaped area. Such a structural improvement of the present invention, has had an unexpected beneficial effect: An inn plug is blown to form a plug bubble by using compressed air, At that time of transfer to the fill station to inject the plug liquid, in the cavity of the foam-like pit of the molding die, the stretchability of the sheet material is used to reach the required production specification, The distance between the edge of the inner bolt and the edge of the outer bolt forms resistance, which can effectively prevent the bolt liquid from being extruded into the joint between the two molding halves to enter the gap between the embossing lines, eliminate the edges and corners of the flash edges on both sides of the bolt body, have a smooth and rounded appearance, and improve the quality of the suppository product and the comfort of the patient.

Description

technical field [0001] The invention relates to the technical field of suppository manufacture, in particular to a method for forming a traditional Chinese medicine suppository. Background technique [0002] At present, the thrombus-making equipment at home and abroad are all automatic or semi-automatic production lines. The suppository thrombus-making process adopts double-sided adhesive preforming technology. The sheet is molded into a cavity and then transported to the filling and freezing station. Its double-sided bonding forms a cavity. During the preparation process, two joints must be formed at the junction of the two sides, and the mold surface of the forming mold is provided with embossing. The gaps between the embossings make it easy for the plug body to form jagged edges and corners at the joint gaps, causing severe discomfort to patients during use. [0003] The shape of the edges and corners varies according to the material of the sheet used in the product, mai...

Problems solved by technology

However, for "water-soluble matrix PEG", suppository products with water-soluble matrix are not affected by temperature in terms of storage, transportation, on-counter display and patient use, especially in summer and autumn high temperature seasons. Compared with fat-soluble matrix products, they have absolute advantages. However, this type of matrix has a high melting point, a hard texture at room temperature, and obvious edges and corners during molding.
